The Moon and Venus will make a close approach, passing within 0°38' of each other.

From London (click to change), the pair will be visible in the dawn sky. They will rise at 03:49 (GMT), 4 hours and 4 minutes before the Sun, and attain an altitude of 25° above the south-eastern horizon before fading from view as dawn breaks at around 07:26.

At the moment of closest approach, the Moon will be at mag -10.4, and Venus at mag -4.7, both in the constellation Virgo.

The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible to the naked eye or a through pair of binoculars.

The precise positions of the Moon and Venus at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 14h06m00s -09°41' Virgo -10.4 29'40"9
Venus 14h05m20s -10°18' Virgo -4.7 16"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 42° from the Sun, which is in Ophiuchus at this time of year.
